by publication of an identical text or by endorsement, at the latest by April 2015,
and conflicting national standards shall be withdrawn at the latest by April

Introduction
The deleterious effects to be anticipated during the thermal cycling test under
vacuum include:
• outgassing,
• cracking or fracture of materials or assemblies due to sudden
dimensional changes by expansion,
• contraction or pressure,
• short circuiting of electrical wiring,
• overheating of materials or assemblies due to change in convection and
conductive heat transfer characteristics.

Principles
The principles of the thermal test for the evaluation of space materials and
processes is to submit the item to be tested (materials, processes, mechanical
parts or assemblies) to a certain number of thermal cycles, oscillating within an
defined temperature range in order to anticipate and to evaluate the resistance
to deleterious effects as:
• outgassing,
• cracking or fracture of materials or assemblies due to sudden
dimensional changes by expansion,
• contraction or pressure,
• short circuiting of electrical wiring,
• overheating of materials or assemblies due to change in convection and
conductive heat transfer characteristics.
For this purpose the activities related to thermal cycling tests requirements,
specifications, procedures and reports are described in Figure 4-1 and the
related requirements are captured in clause 5.
